CONTEXT Sentinel lymph node dissection (SLND) accurately identifies nodal metastasis of early breast cancer, but it is not clear whether further nodal dissection affects survival. OBJECTIVE To determine the effects of complete axillary lymph node dissection (ALND) on survival of patients with sentinel lymph node (SLN) metastasis of breast cancer. (More)
BACKGROUND AND OBJECTIVE Sentinel lymph node dissection (SLND) has eliminated the need for axillary dissection (ALND) in patients whose sentinel node (SN) is tumor-free. However, completion ALND for patients with tumor-involved SNs remains the standard to achieve locoregional control. Few studies have examined the outcome of patients who do not undergo ALND(More)
American College of Surgeons Oncology Group Z0010 is a prospective multicenter trial designed to evaluate the prognostic significance of micrometastases in the sentinel lymph nodes and bone marrow aspirates of women with early-stage breast cancer. Surgical complications associated with the sentinel lymph node biopsy surgical procedure are reported. Eligible(More)
BACKGROUND This study evaluates the safety, efficacy, and patient acceptance of a vacuum-assisted, hand-held biopsy device (Mammatome) in the percutaneous removal of breast masses using ultrasound guidance. METHODS A multicenter, nonrandomized study evaluated 216 women with low-risk palpable lesions. Lesions 1.5 to 3.0 cm in size were removed using an(More)
BACKGROUND This study evaluates the safety, efficacy, and patient acceptance of a vacuum-assisted, hand-held biopsy device (Mammotome) in percutaneous removal of breast masses using ultrasound guidance. METHODS A multicenter, nonrandomized study evaluated 124 women with low-risk palpable lesions. Lesions <or=1.5 cm and those >1.5 cm but <or=3.0 cm were(More)
BACKGROUND The authors prospectively evaluated the performance of a proprietary molecular testing platform using one-step nucleic acid amplification (OSNA) for the detection of metastatic carcinoma in sentinel lymph nodes (SLNs) in a large multicenter trial and compared the OSNA results with the results from a detailed postoperative histopathologic(More)
BACKGROUND AND OBJECTIVE The early results of the American College of Surgeons Oncology Group (ACOSOG) Z0011 trial demonstrated no difference in locoregional recurrence for patients with positive sentinel lymph nodes (SLNs) randomized either to axillary lymph node dissection (ALND) or sentinel lymph node dissection (SLND) alone. We now report long-term(More)
With recent improvements in breast imaging, our ability to identify small breast tumors has markedly improved, prompting significant interest in the use of ablation without surgical excision to treat early-stage breast cancer. We conducted a multi-institutional pilot safety study of cryoablation in the treatment of primary breast carcinomas. Twenty-nine(More)
BACKGROUND When sentinel node dissection reveals breast cancer metastasis, completion axillary lymph node dissection is ideally performed during the same operation. Intraoperative histologic techniques have low and variable sensitivity. A new intraoperative molecular assay (GeneSearch BLN Assay; Veridex, LLC, Warren, NJ) was evaluated to determine its(More)
BACKGROUND This study compared the surgical results of 2 localization methods-cryo-assisted localization (CAL) and needle-wire localization (NWL)-in patients undergoing breast lumpectomy for breast cancer. METHODS A total of 310 patients were treated in an institutional review board-approved study with 18 surgeons at 17 sites. Patients were randomized 2:1(More)
